Thanks Rob, it's here:

I could delete the other 3 from the device tab and see if everything still functions normally?

Yes, absolutely. But keep a backup though, just for safe keeping.

And just for the record, the 4 codes that got added for the Roksan are:
AMP/3731 = NEC1 32.159 (the one that worked)
AMP/0420 = NEC1 134.97
AMP/0435 = NEC1 134.97
AMP/3732 = $0153 executor, with "FB 06" fixed data and 3 byte button codes

Ok, I deleted the other three and all the amp buttons still work

Let me know if you want to go hunting for discrete codes

Setup code 3731 is NEC1 32.159. Setup 3732 employs a PID 0153 executor, which can send NEC1, RC5, and several variations of another gap IR protocol. I shot the 3732 upgrade at a Widget, and interestingly, Power is sent as NEC1 with the same device and OBC as 3731. The other functions are all RC5 device 16.

Why mention this? Because I suppose that there is a (small) chance that the Kandy2 also responds to RC5 codes, and that the discrete Power signals are only available as RC5. When we get around to searching for discretes, it may be a good idea to temporarily try setup code 3732 to see if the amp responds.

device OBC
RC5 16 16 vol+
RC5 16 17 vol-
RC5 16 12 mute
RC5 16 32 Assigned to TV input (dash)
RC5 16 33 Assigned to Audio Input (button51)

Hi 3FG, thanks for looking into this. Where can I read up on this topic?

ok, so what you do is, you create a new upgrade that uses NEC1 32.159, just like the working upgrade, but you add a bunch of OBCs that are not already accounted for (ie, not 7,14,26,28,29,64,68,72) and then load it into your remote and test all the buttons to see if any of them do anything. It will take several passes to account for all the possible OBCs if you decide to test all the way up to 255.

All Dave is saying is, try testing the 3732 code also to see if it does anything. We suspect that, at the very least, the POWER button will work, but the question is, do any of the other buttons work.

Ok thanks, I'll give it a go

The power button is the only one that works with setup code 3732.

OK cool, thanks for trying.

Btw, did you try searching for discrete codes yet? Do u have a handle on how to do it, or do u need help?

JezW · Post by **JezW** » Wed Dec 02, 2015 2:41 pm

Sure

I think I understand how.

I'm going to go into the device upgrade editor and change all the OBCs on the buttons, then upload to the control and try each of them.

Then plug in and repeat until I hopefully get somewhere

I just realised that if I'm looking for the discrete on and off codes then I need to run through all the way up to 255 whilst the amp is on and off!?

JezW · Post by **JezW** » Wed Dec 02, 2015 3:54 pm

I ran through every code from 0-255 with the amp on and off. It's a good thing you can copy and paste from excel into RMIR, otherwise I would've been typing out all those OBC codes!

Unfortunately no luck, except on the ones we knew already

Only good news is I spotted a mistake from before. I said that the mode button OBC was 7. It's actually 76, I must have missed it off when typing.

Does this mean no discrete codes exist?

Thanks for your help

I hope you created upgrades with more than just 8 buttons, but regardless, if you're sure you tested all 256 codes (from 0 thru 255) then yes, I'm afraid that almost certainly means that there are no discrete codes or any other secret codes.

I say "almost" because it's always possible that the amp responds to more than one codeset, but we have no way of knowing that, so yeah, that's it!
